Direct current motor is an important drive configuration for many applications across a wide range of powers and speeds. It have variable characteristics and used extensively in variable-speed drives. The goals of this project are to control the direction and speed of Direct Current (DC) motor. The Radio Frequency (RF) modules also used to make this project as a user friendliness to control the interface yet make it more useful. This project divided into two part of circuit. First circuit is for transmitter and another circuit is for the receiver. Pulse Width Modulation (PWM) technique is used where its signal is generated by PIC 18F4550. The PWM signal will send to the motor driver to vary the voltage supply to the motor in a desired speed. The DC Motor driver L293D is used in this project as it is a component that has dual full bridge driver where it also can control the direction of the DC motor. A rotary encoder plate is coupled to the end of motor shaft to provide the feedback speed signal to the controller. The RF modules used here are NT-T10A for transmitter module and CWC-12 for the receiver module. Four push buttons are built at the transmitter side as switches to control the speed and direction of DC motor. The four switches are interfaced to the RF transmitter module through PIC 18F4550. 16 x 2 Liquid Crystal Display (LCD) Modules is added at receiving side. It functions to display the outputs or corresponding action that obtain from the PIC 18F4550. In conclusion, the direction and speed of DC motor can be controlled. Plus, this motor controller can be applied as a basis in roboting system, kid's toys and also industrial field.

Scientific Essay from the year 2015 in the subject Engineering - Power Engineering, grade: N/A, , course: Electrical Power Engineering, language: English, abstract: The aimed objective of this Research project is to control the speed and direction of brushless DC (Direct Current) motor, through RF (Radio Frequency) module. Microcontroller is the central part of this project which is controlling all the process i.e. checking for over current, under/over voltage and starting the auxiliary motor (for load sharing) in case of overloading etc. If the motor is having under or over voltage problems then it will automatically be stopped, to protect it from any damages. The process of speed control will be done by PWM (Pulse Width Modulation) technique. & lastly an advantage feature kept is the direction control of this motor.

Direct current (DC) motor has already become an important drive configuration for many applications across a wide range of powers and speeds. The ease of control and excellent performance of the DC motors will ensure that it is widely used in many applications. This project is mainly concerned on DC motor speed control system by using microcontroller PIC 16F877A. Pulse Width Modulation (PWM) technique is used where its signal is generated in microcontroller. The program for PWM generation is written in C+ Language using MPLAB IDE software. It is programmed into the microcontroller using PIC Microcontroller Start-up Kit. Then the microcontroller is installed into the motor control circuit. The Microcontroller acts as the motor speed controller in this project. The PWM signal will send to motor driver to vary the voltage supply to motor to acquire desired speed. Besides, it also shows a graph of motor speed versus PWM dutycycle percentage to let the user monitor the performance of the system easily. Based on the result, the readings are quite reliable. Through the project, it can be concluded that microcontroller PIC 16F877A can control motor speed at desired speed efficiently by using Pulse Width Modulation signal.

Graphics displays are gaining popularity in an increasing range of control and user interface applications in markets such as home automation, home appliance, medical and industrial. These kind of displays enhance the user experience and provide detailed information with sharper images. Additionally, graphics displays enable technologies such as touch screen, leading to more effective and efficient interfaces to the applications. In this work, touch screen technology is being employed for controlling the speed and direction of a DC Motor. ATMEGA32 Microcontroller takes the command from the touch screen and the data is transferred to driver circuit (L293D DC Motor Driving IC) and this data is converted to electrical pulses and is fed to the DC Motor. Pulse width modulation technique is employed for controlling the speed and direction of the motor.
